Has anyone tried revolution flea treatment for dogs?
I have heard from many vets that Revolution if very good for heartworm prevention but sucks as flea prevention. Your dog will need to be current on a hearworm test before you can get that filled. I would try again with the Frontline since it is the best out there if your dog is always in the water. Advantage is actually now water resistant but does not work as well as Frontline. Always wait 2-3 days before or after a bath/swimming to apply the meds. If fleas are a big problem in your area you can reapply Frontline as early as 3 weeks. Good Luck.
